this is a very small 4x4 trial truck with front pendular suspention,ditrction(not functional yet because i have no micromotor,but it will come in the next weeks),powered by an old 9V motor (not powerful enough, will be replaced by a new 9V motor)
transmission:8->24,16->24(by chain),8->1(worm screw),12->20.
I tested it in any field, it is not bad but there is no video because the batteries are dead;Video coming as soon as there are new batteries
Great, quite inspiring, but improvement is far from impossible. Make the front axle stronger, put a free differential in the back (you can put there easily a 3 stud wide one - this modification won't affect off-road abilities but will result in a much better turning circle) and make it rc with power functions. And if you could make the rear axle pendular too and to both add rubberbands for stability. Other than that just congratulations and maybe one you make a mini truck trial organisation!
